Pulse power

Generating power at very high output levels in a short period

Pulse power is a technology that stores/compresses electrical energy to generate power at extremely high output levels in a short period. It finds applications in various fields such as basic science, defense, industrial technology, including high-power lasers, pulsed X-ray generation, particle (electron, ion) beam sources, electron acceleration, and high-energy microwave generation.

PULSED NANO POWDER

PULSED NANO POWDER
  • Nano powder synthesis systems in which a pulsed magnetic field is applied to electrodes of precursor materal, in closeproximity to an electrical discharge arc that is formed between the electrodes, to attain increased yields of nano powder.
    A magnet insert of a coating precursor material is used to coat the nano powder andthereby reduce nano particle agglomeration.
PULSED NANO POWDER
  • Nano powder particle production by electromagnetic pulse
